PSA Overview J2EE

This example deals with the domain of professional services automation, also known as PSA. PSA is a set of software and services used by professional services organizations to help operate more effectively. PSA may cover a wide range of processes,including project bidding and team,skill,project,and customer management.

Our intention with this example is to address a small set of basic requirements of a professional services organization. The PSA system must be flexible,providing different services based on the particular role of the user.

  • Project managers will search the PSA system for matching resources, check on the availability of a particular resource, and schedule an available resource for a specific project.
  • Consultants(hereafter known as “resources”) accept and manage their assignments,their availability,and the listing of their current skill set.
  • Project administrators are “super” project managers,as they can act on behalf of a project manager.In addition,they perform administrative tasks, such as creating new projects and managing the care and feeding of project information over its lifetime.

Each of the three roles share common functional requirements:

  • Searching based on projects,resources,skills.
  • Managing resource information(address,email,phone,etc.).
  • Other packaged and ad hoc reports and queries.
